HYDRAUIA|C-NOZZLE AND GATE.

SPECIFICATION 'forming part of Letters Patent No. 352,732, dated November 1G, 1886.

- Application filed November 23, 1885. Serial No. 183,781. (No model.) i

To aZZ whom it may concern:

Be it known that I, JAMES H. BYRNE, 'of Nevada City, Nevada county, State Vof California, have invented an Improvement in Hydraulic Nozzles and Gates, and I hereby declare the following'to be a full, clear, and exact description of the same.

My invention relates to hydraulic nozzles and gates, which are especially adapted for use Io in connection with that class of wheels which are driven by a jet or stream of water delivered into the buckets of the wheel through a nozzle connected with the pipe which brings the water from a high-elevation, so as to give it great momentum'. rIfhe pressure of the water is so great that it has hitherto been ime practicable to regulate and alter the size of the `jet without so altering the shape of the delivery-nozzle as to greatly impair its efficiency. My invention consists in the peculiar construction and combination of devices, which I shall hereinafter fully describe and claim.

Referring to the accompanying drawings for a more complete explanation of myinvention, 2 5 Figure 1 is a longitudinal vertical section of the nozzle. Fig. 2 is a front view of the nozzle. Fig. 3 is a rear View oi' the nozzle.

A is the pipe through which water is brought to the nozzle from a reservoir or source 3o of supply, so situated as to produce an enormous pressure. In this pipe, a short distance from the nozzle, is tted a transverselysliding gate, B, which is provided with ascrewshank or stem, C, and an operating-nut and hand- 3 5 wheel, D. A hole is made through the gate, of equal size with the interior of the pipe, and the gate itself extends downward below the pipe, sliding within the seat or case E, which serves as a guide for it, and which may `be left 4o open at the lower end. This extension of the lower part of the gate is of such a length as to more than equal the diameter ofthe pipe, and when the gate is drawn upward, the opening through it passing into the upper part of the y case, the lower portion of the gate will be drawn across the pipe, thus cutting oft' as much of the water-supply as may be desired, and when it has been drawn across they pipe,

so as to entirely cut ofi' the water, the lower edge of the slide remains within the 4case or seat 5o E. This is important, because it prevents the settling of dirt or sediment within the case, which would eventually iill it up and prevent the gate b eing moved into it.

F is the discharge-nozzle,which may be made 5 5 of any suitable or desirable shape. In the present case I have shown it as being of rectangular form and suitably tapered or contracted, so as to discharge a smooth and solid stream from its outer end into the buckets of 6o the wheel G. From the upper rear part ofthe nozzle a vertical guide, H, extends at right angles with it, and within this guide a slotted slide, I, is fitted to move, this slide having a width or thickness equal to the width of this 6 5 nozzle at that point. The upperend of the slide is connected with ascrew-shank, J, passing through a fixed nut and having a handwheel, by which it-m ay be turned so as to raise or lower the slide.

From the foot of the slide I, and forming a part of it, an extension, K, is formed, exactly viitting the `interior of the nozzle and extending to the front or discharge end. The lower part of this extension forms the top of the nozzle, 7 5

.and the front end is always kept in proper form to deliver the diminished stream of water with the best eiect. If desired, the entiref jet of water may be cut off by this adjustingnozzle-without depending upon the gate.

This device is of great value in connection with the class of wheels to'which it is applied,

where itis often necessary to enlarge or dimin- 9o ish the stream of water. Having thus described my invention, what claim as new, and desire to secure by Letters Patent, is-

A hydraulic discharge-nozzle made straight or rectangular in its interior dimensions, and

having one of its sides duplicated, the dupli- In witness whereof I have hereunto set my cate side being movable Wibhinthe nozzle and hand. in a parllel plane, so as to increase or diminish the inside area of the nozzle, in combina- JAMES H.
